ADJUSTABLE LOCK CASING.

Application filed April 7, 1921. Serial No. 459,258.

To all whom it may concern:

Be it known that I SAMUEL SEGAL, a citizen of the United States, and a resident of New York, in the county of New York and 6 State of New York, have invented certain new and useful Improvements in Adjustable Lock Casings, of which the following is a specification.

My invention relates to locks for doors or other closures in which the locking bolt of the lock shall be adapted to interlock with a suitable keeper fastened to the door frame or other support.

The object of the invention is the production of a lock, the casing of which shall be adjustable in any direction without disturbing' or changing the position of the spindle or other means adapted to actuate the lock mechanism and operated by a key from Without the door.

Other and further objects and advantages of the invention will appear from the accompanying description,the invention consisting in the novel parts and combinations 2!! of the same hereinafter more particularly described and then specified in the claims.

In ordinary locks it frequently happens a that the locking bolt is thrown out of alignment with the keeper and will not interlock with the same due to the warping or sagging of the door or door frame or because of other reasons which prevents the lock from functioning until the lock or the keeper is entirely removed and its position read justed. It is to obviate these objections and disadvantages that I have devised mypresent invention.

Referring to the drawings illustrating a practical embodiment of the invention:'

Fig. 1 is a front elevation of a lock casing applied to a door and embodying my invention.

Fig. 2 is a front elevation of a plate fastened to the door and to which the lock casing, is removably secured.

Fig. 3 is a rear elevation of the lock casing.

Fig. 4: is a view similar to Fig. 3 with the cover plate. removed.

Fig. 5 is a front elevation of the cover plate of the lock casing.

Fig. 9 is a vertical cross-section on the line 99 of Fig. 3.

Fig. 10 is a section on the line 10-10 of Fig. 3.

Referring in detail to the drawing:

The casing of a lock is' indicated at 1 and is provided with horizontal slots 2 at that end thereof which extends beyond the edge of a door 3 when the lock is in mounted position on the door. 4 is a locking bolt slidable vertically ontracks 5 within the casing and provided with hooked ends or fingers 6 normally concealed bysaid casing and adapted to span or extend across said slots 2 when in locked position and to interlock with the perforated ears of a suitable keeper (not shown) fastened to the door frame. Said locking bolt is provided with lugs 7 thereon with a space 8 intermediate said lugs and with apin 9 secured thereto. A tumbler pawl is indicated at 10 and is pivoted to said locking bolt l as at 11. Said tumbler pawl is provided with an arm 12 normally extending within the space 8 intermediate the lugs 7 and with a shoulder 13 normally engaging a post 1 1 fastened to the outer wall of the casing. A spring 15 is secured to the upper end of the tumbler pawl 10 and engages the pin 9. The action of said spring tends to swing the tumbler pawl 10 on its pivot 11 in a clockwise direct-ion whereby the-arm 12 will extend intermediate the lugs 7 and the shoulder 13 will engage the post 14;. The engagement of said shoulder and post holds the locking bolt in raised and unlocked position in an obvious manner.

16 indicates an operating knob mounted on the front wall of the casing and provided with a shank extending through-said wall to which is secured the operating fingers l7 normally held in vertical alignment and in inoperative position by a spring 18, fastened'to a wall of the casing. To throw the operating bolt into locked position the knob 16 is turned or rotated against the action of spring 18 which causes one of the fingers 17 to first engage and press against the arm .12 swinging the tumbler pawl 10 on its pivot 1L in a counter-clockwise direction against the action of spring to release the shoulder 13 from engagement with post 14. Further movement of the finger 17 causes the same to engage and press downwardly against the lower lug to cause the locking bolt 4 to slide downwardly on the tracks 5 whereby the hooks or fingers 6 are thrown into locked position across the slots 2. When the locking bolt reaches its lower or locked position a shoulder 19 thereon engages the under side of post 14 to hold the bolt in this position.

\ To raise the bolt into unlocked position the reverse movements of those just described are effected by manipulation of the knob 16 which requires no detailed description as this type of bolt is old in the art and its operation is now well understood.

20 indicates a cylinder of an ordinary pin tumbler lock mounted in an annular opening 21 in the door 3, and carrying on the forward end thereof a conventional form of escutcheon plate 22 engaging the outer face of said door. Said cylinder is provided with the usual ears 23 preferably integral therewith and extending laterally therefrom. The door is provided with a shoulder 24 adjacent the end of the opening 21 on which is seated a plate 25 provided with an opening 26 therein. The cylinder is held in mounted position in said annular opening 21 by means of screws 27 which extend through said plate 25 and which are threaded through the ears 23. 28 indicates a spindle operatively connected with the key plug (not shown) of the cylinder and which is adapted to be rotated to actuate the lock mechanism when the proper key is inserted in said key plug from without the door and is rotated as is well understood in the art. Said spindle extends through the opening 26 in the plate 25 as clearly shown in Fig. 6.

A removable cover constituting the rear wall of the lock casing 1 is indicated at 29. Said cover is adapted to be fastened to said casing by a screw 30 extending therethrough and threading within the post 14. Said cover is provided with slots 31 and with 'an enlarged annular opening 32 within which is mounted a rotatable ring-shaped actuator 33 extending therethrough and provided with a flange 34 engaging the inner face of the cover, said flange being provided with an actuating finger 35 adapted to engage the lugs 7 and arm 12 to actuate the lock mechanism in the same manner as the fingers 17. The opposite side of said actuator is provided with a flange 36 engaging the outer face of the cover 29, said flanges 34 and 36 acting to retain the actuator 33 in mounted position in the opening 32 in said cover and prevent its Withdrawal therefrom. 37 indicates a ring secured to the flange 36 by pins 38 whereby a space or slot 39 obtains intermediate said flange and ring. A flat bar 40 provided with a slot 40 is slidably mounted in said space 39 and is capable of movement therein in all directions limited in some cases by the pins 38 which act as stops.

41 indicates a plate which is securely fastened to the door by means of screws 42. Said plate is provided with ribs 43 on the inner face thereof contacting with or engaging the door to leave spaces between said plate and door. 44 indicates enlarged rectangular openings in said plate and 45 is a depression provided with an enlarged annular opening 46 therein.

The lock casing is secured to the plate 41 by means of screws 47 passing through the front wall of the casing, through the slots 31 in the cover thereof, through the rectan gular openings 44 and threading through bars 48 which are interposed between the plate 41 and the door intermediate the ribs 43 and which are of sufiicient length to permit them to span the rectangular openings 44 and to prevent their withdrawal through said rectangular openings. The ends of the screws 47 do not enter the door but the lock casing is firmly held to the plate 41 by the binding action of the bars 48 against the inner surface of said plate, the ribs 43 acting as stops to prevent rotation of. said bars when the screws 47 are tightened or loosened.

The operating spindle 28 not only extends through the opening 26 in the plate 25 but also through the enlarged opening 46 in the depression 45 of the plate 41, through the ring 37 and through the slot 40 of the bar 40. When said spindle is rotated by means of a key inserted in the key plug from without the door the bar 40 is also of necessity rotated and its ends or the parts thereof adjacent its ends thereupon engage and press against the pins 38 to effect a rotation of the actuator 33. The actuating finger 35 is thus rotated to actuate the lock mechanism as previously described.

It will be obvious from the foregoing description that the position of the lock casing may be adjusted in any direction either vertical, horizontal or diagonal without it being necessary to remove the casing and without changing or tampering with the pin tumbler portion of the lock or the operating spindle 28 thereof or the lock mechanism within the casing. To efl'ect a change of position of the casing the. screws 47 are merely loosened and the casing moved to the desired position, after which the screws are tightened to securely hold the casing in the adjusted position in the manner previously described. The large rectangular openings 44 through which the screws 47 extend permit the casing to be moved in any direction for a material distance. Also the movement asaraa or adjustment of the casing in any direction for a ma e a stanc may be efi e With o t nt e nce w h t Op ra ing Spind e 2 du o h la ge iz of th openi g .44 and ring 37 through which the spindle extends, h sp n i l ays pe i y connected to the actuator 33 even when the posit wo t e asing s adjusted s he ba t i capa e of mov ment n ny rect n thou bec m g d sengage f em aid ctu t a has b exe eda A l be also noted the plate llis of a size permitting access to be had to the screws 42 by loosening thescrews 47 and shifting the position ofthe casing even though the casing issecuredto said plate so as to permit said casing. and plate to be removed as a unit when so desired. This isof advantage as itmakes for convenience of installation.
